Technical field:
The present invention relates to building field, relate in particular to lockset, particularly a kind of improved anti-theft safe lockset structure.
Background technology:
Why stolen easily motorcycle, power assist vehicle, battery truck, bicycle be, all because outside the stem stem of light lockset of the prior art is exposed to, the king bolt cutter can brute force be twisted into two parts the stem stem pellet shot from a slingshot after inserting the stem stem groove, or instigate the stem stem pellet shot from a slingshot with master key, or strike with hammer and to pound, to make the crooked dead bolt that breaks away from of snap close, also useful locking pliers is cut off lock ring, and therefore light lockset of the prior art is insecure.
Summary of the invention:
The purpose of this invention is to provide a kind of improved anti-theft safe lockset structure, described this improved anti-theft safe lockset structure will solve in the prior art light lockset stem stem and be exposed to outer, unstable technical problem.
This improved anti-theft safe lockset structure of the present invention is by lock ring, lock cylinder and transverse tube constitute, described lock ring is the U type, one end of lock ring is connected with an end of described transverse tube by bearing pin, described lock cylinder is made of shell body and stem stem, be respectively arranged with the pellet shot from a slingshot hole in the mating face of shell body and stem stem, be provided with pellet shot from a slingshot in any one described pellet shot from a slingshot hole, be provided with spring in the pellet shot from a slingshot hole of shell body, be provided with the key slot in the described stem stem vertically, wherein, be provided with lockhole in the sidewall of the other end of described transverse tube, the other end of described lock ring penetrates described lockhole, be provided with breach in the sidewall of this end of lock ring, described lock cylinder is arranged in the transverse tube, described shell body is fixedlyed connected with transverse tube, the tail end of described stem stem is fixedly connected with a snap close rod member, described snap close rod member is positioned at described breach, be provided with an axial groove and a radial slot in the sidewall of transverse tube, described radial slot is parallel to the radial section of transverse tube, one end of axial groove and radial slot is interconnected, axial groove and radial slot are all on the front end and the transverse tube sidewall between the described bearing pin of stem stem, one end opening of described key slot is in the breech face of stem stem, be set with a fixed head in the tail end of stem stem and the transverse tube between the lockhole, described fixed head is axial perpendicular to transverse tube, be provided with one first through hole in the fixed head, described snap close rod member passes described first through hole, also be provided with one second hole in the fixed head, be provided with a blind hole in the breech face of shell body, in the gap between described second hole and blind hole, be provided with a removable pin, one end of described removable pin is positioned at described blind hole, removable pin is fixedlyed connected with a spring leaf, and an end of described spring leaf and the tail end of stem stem are fixed.
Further, be provided with key in the described key slot, described key is made of flute profile bar and handle bar, and an end of flute profile bar is the L type with an end of handle bar and is connected, and the width of described radial slot is greater than the width of handle bar.
Operating principle of the present invention is: but lock ring constitutes the closed-loop structure of folding by bearing pin and transverse tube, after the other end of lock ring penetrates transverse tube through lockhole, rotate the snap close rod member of its tail end by the stem stem of lock cylinder, the snap close rod member snaps in the breach of this end of lock ring, prevent that lock ring from withdrawing from transverse tube, realize locking.The flute profile bar of key is inserted stem stem in the transverse tube by axial groove, in radial slot,, can rotate stem stem along the handle bar of circumferential mobile key.Further, spring leaf stops stem stem to rotate with in the removable pin compressing blind hole in the shell body breech face, the key flute profile bar of correct length removable pin can be released the blind hole of shell body breech face and move to fixed head and the shell body breech face between.Long flute profile bar will push second hole in the fixed head to removable pin, thereby stop stem stem to rotate.
Concrete, the structure of the lock cylinder among the present invention can adopt known configurations of the prior art, relevant lock cylinder known schemes in the prior art, and those skilled in the art all understands, and does not repeat them here.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is built in lock cylinder in the transverse tube, can prevent that the king bolt cutter from directly inserting stem stem, spring leaf and removable pin are set between shell body tail end and transverse tube, constitute double insurance mechanism, can after master key is successfully instigateeed the stem stem pellet shot from a slingshot, continue to stop stem stem to rotate.Lockset is firm, anti-destruction, and safety promotes greatly.
